PLAlTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 331,432, dated December 1 1885,

Application filed February 24, 1885. Serial No. 156,686. (No model.)

To all whom it may concern:

Be it known that I, FRIEDRICH PANSE, of the city of New York, in the county and State of New York, have invented a new and Improved Plaiting-Machine, of which the following specification is a full, clear, and exact description.

This invention relates to a machine for plaiting crimped or fluted fabric. The plaitingmachines heretofore in use were made for the manufacture of plaits out of plain fabric, and the fabric was generally stretched between two needles or plates while the plait was formed. With crimped fabric the stretching would be impracticable, inasmuch as the crimps would thereby be straightened out.

The invention therefore consists, principally, in the combination of two gage-plates so arranged that the fabric is made to form a loose fold between them, the fold being afterward pressed and treated in proper manner to form the plait. I

The invention also comprises mechanism for throwing the fabric up between the gageplates and for adjusting the size of the folds.

It also consists in the various features of improvement hereinafter more fully pointed out.

In the accompanying sheets of drawings, Figure 1 is a top View of the machine. Fig. 2 is a vertical section on the line a: m, Fig. 1. Fig. 3 is a detail view of the gage-plates and intervening presser-foot and spring; Fig. 4, a side view of the machine, (left side of Fig. 1;) Fig. 5, a detail sectional view of the feed mechanism; Fig. 6, a front View of the machine above the work-plate, (the front gage-plate being removed 5) Fig. 7, a partial bottom view of the work-plate; Fig. 8, a detail view of the front gage-plate. Fig. 9 shows the crimped fabric as it enters the machine, and Fig. 10 the completed plaiting as it leaves the machine.

The letter A represents the machine-frame, carrying a horizontal work-plate, a. b is the front gage-plate, and c the rear gage-plate. The gage-plates are constructed in such a manner that the front plate grasps the fabric and pushes a fixed portion thereof toward the rear plate. Between the plates when they are brought together a narrow space or chamber, d, always remains, and the fabric bulges up in this space to form a fold. This fold is subsecrating and adjusting the gage-plates and the 1 supplemental devices for forming the fold.

A power-shaft, B, is hung across the machine, and may be revolved by hand orotherwise. A cam, e, on this shaft imparts, by toggle-levers f f, intermittent partial revolutions to a shaft, hung across the front of the machine. To the shaft 9 are keyed two arms, h, and to trunnions on these arms are in turn pivoted two rods, 1', to which the front gageplate, I), is rigidly secured. By operating the power-shaft as thus far described horizontal reciprocating motion is imparted to plate I). The rear gage-plate, c, is free to move vertically up and down between stationary guides. It receives its motion from a shaft, j, to which it is connected by means of arms it, that are keyed to the shaft and swiveled to the gageplate. The shaft receives intermittent partial revolutions by suitable cam-connection with the power-shaft B.

Z Z are two pins attached to and projecting forward from the face of gage-plate 0. These pins engage beneath two lugs, m, formed on the gage-plate b, Fig. 1, and form ways on which the plate 1) slides to and fro.

As the front plate has a swivel-connection with its shaft it is evident that the plate is free to rise and fall, and thus as the rear plate,

c, rises it will force up plate I) by means of 8 5 pins Z, while when the plate 0 falls the will likewise fall by gravity.

After a length of fabric is introduced into the machine a partial revolution of the powershaft will bring the gage-plates into the position shown in Fig. 3-that is to say, the plate bis in its foremost position, and both it and plate a are in their lowermost position. A further motion of the work-shaft will now cause the plate I) to move toward plate 0. In this motion the plate b, turning on the trunnions, will assume a more and more vertical position, its lower edge sweeping across the work-plate. The plate I) is finally brought into the position indicated by dotted lines in Fig. 3, in which it is at its closest proximity to plate 0. In this position both plate b plates are substantially parallel, both are in their lowermost position, and between them the empty space or chamber (1 is formed. During the advance of plate b it has grasped the fabric under its lower edge and crowded it along with it, so that all the fabric between the plates in their most distant position is collected in the space (1. Thus the fabric forms an upwardly-proj ecting loose foldin said chamberd. After the plateb has advanced in manner described both plates are raised, (plate 0 by shaft j, and plate b by pins 7,) and the plate b is moved back into its first position.

The motion of plate b is capable of double adjustment. The first is designed to change the size of chamber d,or, in other words,to regulate the minimum distance between plates b c. The second permits the outward throw of plate b to be altered, so that a greater or less quantity of fabric is grasped. The first adjustment is obtained by varying the length of arm f. To this effect the arm f is made of two pieces, Figs. 1 and 4, connected by a bolt that passes through a slot in one of the pieces. The second adjustment is obtained by a screw, a, passing through the front of the machineframe. The end of the screw strikes against the lower end of the arm f, and thus by turn ing the screw in or out the arm f (and consequently plate b) is permitted to move forward to a lesser or greater extent.

D is the presser-foot, placed between plates b c. This foot reciprocates vertically between stationary guides and receives its upward motion from a cam, 0, while springs p throw it down. When the gage-plates are brought together, the presser-foot descends and bears upon the center of the fold just formed. Beneath the presser-foot is the reciprocating feedrack hereinafter described, and as the gageplates rise to release the fabric the presser-foot holds it against the feed. After the feed ceases to act the presser-foot is raised to the position shown by full lines in Fig. 3. The gage-plate b is slotted, Fig. 8, to permit the presser-foot to project forward of said plate when the plates b c are in proximity. Between gageplates b c the work-plate a is provided with two slots, Figs. 1, 3, and 6, and through these slots project two (more or less) fiat upwardly-curved springs, q. These springs serve to bulge the fabric between the plates as the plate b advances. On the return motion of plate b the springs q are made to descend beneath the work-plate, so as to be out of the way. To this effect they are connected beneath work-plate a to a rod, 1", Fig. 7, the

ends of which project upwardly through apertures in said plate. These ends are directly beneath the presser-foot plate D, and thus as the latter descends the ends of rod 1" are pushed down. The rod in turn will force the springs q down.

The feed acts beneath the presser-footD,and also beneath a second presser-foot, E, placed directly back of foot D. The foot E is free to rise and fall. It presses the middle of the plait against the feed, and is heated by gas led into its interior, so as to fix the plait in its compressed condition.

The feed consists of a toothed rack, F, to which reciprocating and oscillating motion may be imparted. The means shown in the drawings, Fig. 5, consist of a cam, s, and block it, to the front of which the rack is attached. The block it is pivoted to the machine-frame, the pivot passing through a longitudinal slot in block it. As the cam revolves, it bears against the rack and raises it. Then the edge of the cam bears against edge of block t, and causes the rack to move in its raised position. As soon as the cam has turned far enough to release the edge of the block the latter is thrown forward by a spring, 14, while the rack F falls down.

The relative operation between the presserfeet and the rack is as follows: After the fold has been formed between plates b cin manner described both presser-feet are down. The rack F is then raised to grasp the fabric, and it begins its motion, carrying the fabric with it. After the backward motion of the rack ceases the presser-foot D is raised,and the rack then swings downward and comes forward. The foot E,resting upon the rack,is raised with the same, and falls down as the rack descends.

The machine is to be provided with an attachment for pressing threads over the flattened part of the fabric. Two parallel threads are fed between rack F and presser-foot E, and are secured to the fabric by pressure and heat or by other suitable means. This, however, has already been described in my Patent No. 214,7 88, and forms no part of the present invention. In place of springs q, I may employ lugs projecting upward from the workplate.

I claim as my invention- 1. The combination of gage-plate c, receiving vertically-reciprocating motion from. a power-shaft, B, with gage-plate b, which receives horizontal reciprocating motion from said power-sh aft, the plates being substantially parallel when at their greatest proximity, substantially as specified.

2. The combination of gage-plate c with gage-plate b, which receives horizontal reciprocating motion from power-shaft B, and with work-table a, the plate b bearing upon said table when approaching plate 0 by connection with said power-shaft, substantially as specified.

4. The combination of plate 0, operated from shaft B, with slotted plate b, operated from said shaft, and with presser-foot D, the latter projecting through the slot in plate b when said plate is in proximity with platen, sub-' stantially as specified.

5. The combination of shaft B with levers ff, the lever f being sectional, and with shaft ITO g, imparting motion to plate 12, substantially as specified.

6. The combination of shaft 13 with levers ff, shaft 9, and plate I), connected to said 5 shaft, and with screw n, bearing against lever f, substantially as specified.
